Single socket tee, designed to give a 90 degree butt joint between two tubes. Frequently used for the joint between end uprights and middle rail where the railing site is straight and level. Also used for base ties on racking. This fitting cannot be used where the tube passing through the sleeve is required to be jointed within the fitting. Used in DDA applications where the 555-8 Top Fix Rail Assembly is used to attach railing to posts and where railing needs to “d-return” and attach to the end post(s). *Only to be used if no mid-rail is being used.
*It is suggested to use a mid-rail.
